The segment, as you can see above, is about how less-than-enthusiastic some Republicans have been in their endorsements of likely GOP presidential nominee Mitt Romney.

One of McCain's endorsements of Romney in January was so enthusiastic that he actually endorsed President Obama, until Romney came over to let him know he had the wrong guy.

"I am confident with the leadership and the backing of the American people, President Obama will turn this country around," McCain said. "We believe in America, we believe that our best days of us. Presid.. excuse me -- President Romney, President Romney."

Less-than-stellar Romney endorsements by former President George H.W. Bush, Congressman Paul Ryan, Senator Marco Rubio, and former New York Governor George Pataki were also featured in the segment.
